I use GPRS MODEM to connect to PC through serial port, and want to send the following data to mobile phone through MMS. 0.000 -0.145 -0.065 0.003 -0.145 -0.065 0.006 -0.145 -0.065 0.008 -0.145 -0.065 ...
1. Cooperate with others. Take our hardware engineers as an example. When testing, software cooperation is generally required. A task that is extremely complex for hardware may be just a few lines of ...
I recently used DSP2808 to make a 3.2 TFT LCD. The GPIO output is correct, but the TFT has no display. Please help~~This TFT works normally on ARM~
Is there any professional who can help?...
Comparators look fairly simple. They compare two signal voltages and set the output high or low accordingly. However, if the two input signal voltages are very close, even a little noise on the input ...
Magnetic resonance imaging (MRI) systems can take high-resolution cross-sectional perspective images of the human body, providing very useful information for medical diagnosis. The radio frequency pro...[Details]
Medical and industrial applications often require isolation voltages of 2500Vac or higher for patient and equipment operator safety. The isolation barrier must not only transmit power to the sensin...[Details]
Until now, designers have faced a trade-off in ADC selection. Pipeline converters offer high resolution and wide dynamic range, but their power consumption is quite high. The alternative, discrete ...[Details]
